Results from our forumRe: Natural selection is proven wrong... formed? Good grief... You make it sound like particle physics is something people do in kindergarten! A civilization that is even able to study photons with more precise methods than a lens and a prism is already an extremely advanced one. When you are as close to understanding the basic essence ...

Re: Why does chlorophyll always fluoresce in red?... When striked by a red photon, chlorophil changes to that lower excited state and to get to the basal state it looses energy by re-emitting red photons. Thats why chlorophil a always fluoresce on red...

Re: What is the exact definition of life?... just is an atom of their organism. Considering these, defining life become more and more difficult. Our Sun and other fixed stars, maybe just photons for other living organisms in universe. The proton, maybe just a very large galaxy for other very small living forms. Then how can we define ...

The two stages to photosynthesislight dependent and light independent reactions. Light dependent is when chemical energy is created, this is fueled by the photons emitted by the sun. Example ATP is formed. Light independent reactions: when the chemical energy is used to create carbohydrates to "feed" the ...

Why are leaves green?... what the absorbtion spectrum is, because all colors are present. But in the morning and in the evening red light is present as the majority of photons making up the spectrum of the sun. And blue light? Well, since the energy of blue light is the highest, blue light is the only one that can ...
